Man shot and killed in Berkeley hills identified

BERKELEY -- Authorities on Monday released the identity of a man shot dead in the Berkeley hills Sunday.

Police say 21-year-old Alverto Santana-Silva of Fremont was shot and killed at 5:40 a.m. after apparently trying to break up an altercation among a group of people hanging out on Grizzly Peak Boulevard near Centennial and South Park drives.

After the altercation, a man left the scene, returned a short time later and shot Santana-Silva, said Lt. Marc DeCoulode of the UC Berkeley Police Department. Santana-Silva was pronounced dead at the scene. It's unclear what prompted the altercation, police said.

Police did not have a complete description of the suspected shooter.

Police are also looking for a Chevy Capri or similar model and a white Chevy Suburban or similar SUV that may be associated with the shooting. Police ask anyone with information about the suspect or the shooting to call 510-642-6760.
